How long before i can play basketball after having dislocated kneecap?

Depends: Depends on the severity of dislocation and associated injuries. It can be anywhere from a few weeks to several weeks. Consult an orthopedic sports surgeon.

About 6 to 12 weeks: If this is a first time dislocation bracing and physical therapy usually is tried first. If there are no other injuries such as cartilage damage you maybe able to return to sports as early as 6 weeks, but more typically about 3months. There is a 50% recurrent dislocation rate after 1 patellar dislocation. If that happens surgery is needed to address the instability. Best to consult a sports doc.

Variable: Each person recovers differently after a kneecap (patella) dislocation. It depends on how much damage was done the knee at the time of dislocation. It can take anywhere from 1 week to 12 weeks to resume function enough to play baseball. Typically any damage manifests as swelling inside the knee. Swelling inhibits the quad muscles. After the swelling goes down, the quads have to return to function.

3 months: Typical recovery from a first-time patellar dislocation that does not require surgery is about 3 months. Many factors determine one's rate of return including level of pain, swelling, range of motion, quad strength and functional status.
